I am trying to deploy to Heroku but get this error:
remote: ** (File.Error) could not read file "/tmp/build_955..e8bf5/apps/koko/config/prod.secret.exs": no such file or directory
I’ve configured the secret key base using environment variables. There is the line
apps/koko_web/config/dev.exs, but that shouldn’t affect things.
What am I missing?
